| Sumario: | There is currently a power shortage in the electric grid around Uppsala, which obstructs the local development, since it prevents companies from expanding their businesses. Sportfastigheter is a part of Uppsala municipality and operates the ice halls at Gränby Sportfält, which occasionally require large power outputs. The purpose of this study is, therefore, to examine whether flow batteries could be a possible technique to redistribute the power output from the electric grid. Type, size and steering of a flow battery have been examined through simulations. Flow batteries have also been compared to other energy storage methods and the implementation of a possible capacitor bank has been investigated. The result is, that flow batteries is a possible technique to cut power tops at Gränby sportfält, while other storage methods should be investigated more closely, since flow batteries is a rather new and unproven technique. If the installation would be made today, a more established storage method such as lithium ion batteries would be preferable, even though flow batteries have a promising future potential. The installation of a capacitor bank can be considered since it would compensate the reactive effect and, hence, reduce the power output at Gränby Sportfält. |
